DReb% is simply a team's defensive rebounds divided by their total defensive rebound "opportunities" - to be specific, DReb% = defensive rebounds / (defensive rebounds + opponent offensive rebounds).
Rebounding percentage: Defensive Rebounding % and Offensive Rebound % are our go-tos to see how a team is rebounding. eFG% is equal to (2pt FGM + 1.5* 3pt FGM) / FGA, since three-pointers are worth 50% more than twos.

(A possession could either end in a field goal attempt that is missed or rebounded by the defense, a turnover, or a free throw - Ken Pom determined that the average number of free throws per trip is just a shade under 2, explaining the ".475."Įffective field goal percentage: This is a way of calculate a player's shooting percentage that solves that issue of Nolte hoisting threes, and Tobey banking twos. These could all be calculated from a simple box-score! If you want to calculate possessions in a given game, the best approximation to use is: Possessions=(FGA-OREB)+TO+(.475*FTA). The short version: There is far too much randomness for this to be meaningful in a 40 minute game. Context matters.Ĭiting +/- information from a given game: Ken Pomeroy wrote more on this than we'll get into here. Remember, players who shoot lots of three-pointers may shoot a lower %, but be more efficient. To know the answer, you'd have to be told more: Nolte shot 8 three-pointers and made 4. (Hat tip to for first showing me the light, years ago).Ĭomparing shooting %s.without context: If Evan Nolte and Mike Tobey both scored 12 points on 50% shooting, who had the better game, scoring wise? (Hint: They may not have been equal). (For the same reason, teams that force many turnovers will tend to have fewer rebounds). If the Hoos just don't miss, their opponents will get very few rebounds, and it's not the fault of how they're playing on the boards. Remember, it's far easier to rebound misses on defense than offense (and impossible, obviously, to rebound after a possession ending in a made basket). And, while this is all very well and good, they've just told you very little about which team is rebounding better. Using Rebound Margin EVER: "UVA isn't just outscoring Virginia Tech 30-10 at halftime, but they're outrebounding the Hokies 14-4 also!" is something you will likely here an announcer exclaim this season.
So, if Joe Harris averages 20 ppg this season, while PJ Hairston averages 21, Harris is actually averaging significantly more points on any given possession. As a rule of thumb, the slowest teams (UVA) will average 10% fewer possessions than the NCAA average, while the fastest teams (UNC) will average 10% more. Per game stats are heavily influenced by the amount of possessions recorded in a game. However, do use caution using ppg averages to compare players across teams. If Joe Harris scored 25 points in a matchup, that's something to report.
And we aren't QUITE so pretentious to ignore it here. We'll all be loyal KenPom disciples in no time! The best places to go to use these are (best place to track live tempo-free stats) and (for ratings and projections).Ĭomparing Points (or rebounds or steals or ANYTHING) per game: Points scored is the easiest and most common stat cited when analyzing how a player performed in a game. Then, I'll introduce some alternatives that we use at STL, and why they give us a fuller understanding of the game. So, don't make us look bad! Avoid any statistics that aren't adjusted for pace.įirst, I'll discuss why it's important to think critically about the numbers that you may see most commonly referred to in the media. Because different teams play at different tempos, their games will have varying numbers of possessions in which they have the opportunity to garner statistics.ĭon't be a pacist! Remember - the Hoos play slow, and limit possessions. Tempo-free stats are statistics that, well, don't use tempo. And, second of all, it's the best way to compare players who may play in different systems or are used in different ways. We do this because, first of all, it makes us look better. We here at Streaking the Lawn are strong proponents of using tempo free statistics to analyze college basketball.
